The .300 Winchester uses the same case head design of the .375 H&H Magnum, its parent cartridge. For four ammunition manufacturers the cartridge case capacities are provided as: Norma 95.5 grains of H2O (6.19 ml), .300 Winchester Magnum SAAMI cartridge dimensions. This translates to about 20% greater energy advantage over the 30-06 Springfield cartridge. The projectile diameter should be 0.309 in (7.85 mm) [8]. https://en.wikipedia.org/w/index.php?title=.300_Winchester_Magnum&oldid=1025234925, Short description is different from Wikidata, Articles with unsourced statements from March 2021, Articles with unsourced statements from July 2019, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 May 2021, at 13:31. The maximum point blank range for the 12 g (180 gr) bullet is 300 yards when zeroed at 232 metres (254 yd). [7], The .300 Winchester Magnum's high availability in popular rifles such as Winchester's Model 70 and Remington Model 700 made the cartridge a popular choice among the shooting public. The .300 Winchester Magnum was designed with a neck which is shorter than the diameter of its bullet. As the bullet will take up volume which could have been taken by the propellant velocity advantages diminish as the weight of the bullet increases. This created the much criticized short neck of the .300 Winchester Magnum. Load Data &Technical Information by Caliber. Since its introduction the cartridge has remained extremely popular. To help differentiate it from the other .300 magnums, and to allow for the chambers of the standard length .300 magnums to be rebored to the .300 Winchester Magnum chamber dimensions, Winchester moved the shoulder forward and lengthened the cartridge slightly. In C.I.P. Winchester developed the .300 Winchester Magnum by taking the .338 Winchester Magnum, which was introduced in 1958, and moved the shoulder forward by 4.0 millimetres (0.156 in) and lengthening it by 3.0 millimetres (0.120 in). Maximum effective range is generally accepted to be 1,210 yards (1,110 m) with ammunition incorporating low-drag projectiles. Wildcatters soon produced the .30-338 Winchester and Norma Projektilfabrik, who were by now manufacturing ammunition for Weatherby, took the standard length basic Weatherby brass and necked it down to .30 caliber (7.62 mm) and called it the .308 Norma Magnum. On the other hand, recoil is subjective (some are more sensitive to it than others) and one can get used to it with practice. Due to the power and performance of the .300 Winchester Magnum cartridge the cartridge is more likely to be employed by specialist units within a police department rather than as a general service weapon issued to law enforcement agents. defines the common rifling twist rate for this cartridge as 254 mm (1 in 10 in), 6 grooves, Ø lands = 7.62 mm (0.300 in), Ø grooves = 7.82 mm (0.308 in), land width = 2.79 mm (0.110 in), and the primer type is large rifle magnum. C.I.P. 300 WSM Cartridge Information. Due to the short neck, heavier bullets particularly those weighing greater than 13 grams (200 gr) and mono-metal bullets such as the Barnes X bullets will need to be seated more deeply into the cartridge. [4] It is a popular selection for hunting moose, elk, and bighorn sheep as it can deliver better long range performance with better bullet weight than most other .30 caliber cartridges. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. Both black bears[14] and grizzly bears[15] are hunted using the cartridge. Beginning with the .270 Weatherby Magnum in 1943, Roy Weatherby introduced a line of cartridges that while based on the Magnum H&H case were shortened to fit a standard length (2.5 in [63.50 mm]) action. SAAMI recommended a six-groove barrel with each groove being 2.8 millimetres (0.110 in) wide. Its recoil is about 30% greater than that of the .30-06 Springfield,[11] which is known as a 'stout' cartridge. [17][18][19] The 3.55 in (90.2 mm) long MK 248 MOD 1 or alike ammunition is not offered commercially, since it exceeds SAAMI standards for overall length and maximum chamber pressure. Only the .300 Winchester Magnum was to survive as a readily available cartridge. [27] However, by the time Winchester got around to designing their own .300, the .308 Norma Magnum and the .30-338 were already on the scene. The U.S. government purchased MK 248 MOD 1 .300 Winchester Magnum match-grade ammunition in 2009 for use in adapted M24 Sniper Weapon Systems and other .300 Winchester Magnum sniper rifles like the U.S. Navy Mk.13s. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 220 gr (14.26 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 2,850 ft/s plus or minus 50 ft/s (869 m/s ± 15.2 m/s). The SAAMI specification .300 Winchester Magnum case capacity is 91.5 grains of H2O (5.93 ml). The .240 Weatherby Magnum was developed in 1968 by Roy Weatherby.In the development of his own .240in/6 mm cartridge, Weatherby was significantly influenced by both the success and the limitations of the .244 H&H Magnum cartridge devised in England by his friend and colleague David Lloyd.It was the last cartridge to be designed by Roy Weatherby. The ammunition standards organizations SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) and C.I.P. The Chattanooga Police Department[24] and Minot Police Department S.W.A.T units[25] and the L.A. County Sheriffs Department's Special Enforcement Bureau[26] which have adopted the .300 Winchester Magnum in some capacity. Bullet weights of 10.7–13.0 grams (165–200 gr) are the preferred choices for these game species. SAAMI recommends a bore diameter of 7.6 millimetres (0.300 in) and a groove diameter of 7.8 millimetres (0.308 in). [citation needed] However, bullets weighing between 7.1–16.2 g (110–250 gr) are available to the reloader for the .300 Winchester Magnum. This caused the cartridge to have a neck shorter than the diameter of the bullet. Many consider the .300 Winchester Magnum to be on the lighter side of what is required for the largest bears, but hunters have had success with the cartridge against these large bruins.[16]. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship. Although the .300 H&H Magnum, .30-338 Winchester Magnum and the .308 Norma Magnum had a head start on the .300 Winchester Magnum these cartridges soon faded into obsolescence. It is an excellent cartridge choice for all plains game under 680 kilograms (1,500 lb). Few .30 caliber (7.62 mm) standard length cartridges can match the performance and versatility of the .300 Winchester Magnum. The SAAMI Maximum Average Pressure (MAP) for this cartridge is 441.3 MPa (64,000 psi) piezo pressure (54,000 CUP). Elk can weigh as much as 450 kilograms (1,000 lb) and moose 640 kilograms (1,400 lb). Several companies, among them HS precision, Kimber and Remington manufacture rifles chambered for the .300 Winchester Magnum specifically targeted at law enforcement agencies. The Weatherby's standard length magnum case was soon noticed. Almost no divergence between C.I.P. 300 Weatherby Magnum Load Data; 30 Nosler Load Data; 30-378 Weatherby Magnum Load Data; 300 Remington Ultra Magnum Load Data; 7.62x51mm NATO Load Data; ... 190 Grain; 200 - 210 Grain; 220 Grain; Cartridge Information. The ballistic performances based off five grain types for velocity are 3,260 ft/s (165 gr), 3,146 ft/s (180 gr), 3,083 ft/s (190 gr), 3,029 ft/s (200 gr), and 2,850 ft/s (220 gr). The taper of the cartridge was reduced to provide the cartridge with more volume so as to increase its potential powder capacity. Subsequently, Remington has made low-recoil rounds called "Managed-Recoil" available for the .300 Win Mag, which recoil less while providing performance similar to the .30-06 Springfield. The .300 Winchester Magnum is powerful enough to hunt any North American game animal. There has been some speculation that if the cartridge was released earlier, the dimensions of the cartridge would have matched the .30-338 Winchester wildcat cartridge. Bullets weighing 9.7–10.7 g (150–165 gr) are adequate for smaller deer such as the mule deer and white-tailed deer. The popular .30 caliber's omission from that lineup was not missed. regulated countries are currently (2013) proof tested at 537.50 MPa (77,958 psi) PE piezo pressure.[10]. and SAAMI dimensional values exist for this cartridge. The .300 Winchester Magnum (also known as .300 Win Mag or 300WM) (7.62×67mmB) is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963. With the average load for the .300 Winchester Magnum, the recoil energy is roughly 30 ft lbs. Hunters found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 165 grain to the harder hitting 200+ grain selections available from the factory. The lengthening of the case and the move of the shoulder forward over the .338 Winchester Magnum allowed for the reaming of the .308 Norma Magnum or .30-338 Winchester chamber to dimensions of the .300 Winchester Magnum. [citation needed]. According to the official C.I.P. [9] With bullets of good sectional density and ballistic coefficients the cartridge possesses the long range performance necessary to take large game species at extended ranges. The most useful bullet weights for the .300 Winchester Magnum are those weighing between 150–200 grains (9.7–13.0 g). The short neck was thought to hinder accuracy because it would prevent the alignment of cartridge to the bore, but this is rarely an issue either today or when the cartridge was designed. Recommended twist ratio is 1:10 (254 mm). The .300 Winchester Magnum is well-suited for 95% of the world's game. [3], The .300 Winchester is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments. The .300 Winchester Magnum can be used to hunt everything from the dik-dik to the giant eland. 22-250 Remington Ackley Improved Load Data, 223 Win Super Short Magnum (WSSM) Load Data, 243 Win Super Short Magnum (WSSM) Load Data, 25 Winchester Super Short Magnum Load Data, 270 Winchester Short Magnum (WSM) Load Data, 7mm Rem Short Action Ultra Magnum Load Data, 7mm Shooting Times Westerner (STW) Load Data, 30-06 Springfield Ackley Improved Load Data, 300 Rem Short Action Ultra Magnum Load Data, 300 Holland & Holland (H&H) Magnum Load Data, 300 Winchester Short Magnum (WSM) Load Data, 325 Winchester Short Magnum (WSM) Load Data, 358 Shooting Times Alaskan (STA) Load Data, 375 Holland & Holland (H&H) Magnum Load Data, 45-70 Gov’t (Strong Actions Only) Load Data, 45 Colt (Single Action Army & Replicas) Load Data, 45 Colt (Ruger & T/C Contender & Encore) Load Data. Due to its ability to shoot flat and carry its energy efficiently, the cartridge is one of the more favored rounds for African plains game. 30 Caliber Reloading Components. Shop Nosler Products. [20], According to JBM Ballistics,[21] using the G7 ballistic coefficient provided by Bryan Litz, and a Weapon Employment Zone (WEZ) analysis of the XM2010 rifle with various .300 Winchester Magnum ammunition types by Bryan Litz, the MK 248 MOD 1 .300 Winchester Magnum cartridge, when fired at its nominal muzzle velocity of 869 m/s (2,850 ft/s), should have 1,286 to 1,289 m (1,406 to 1,410 yd) supersonic range under International Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m3). Remington 88.0 grains of H2O (5.70 ml) Other cartridges, while available, are more expensive. As a rough comparison, the recoil of the .300 Winchester Magnum is roughly comparable to a 12 gauge shotgun shooting 1 oz. This would put the .300 Winchester Magnum at the upper limit of what most shooters can shoot comfortably for extended shooting sessions. According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,500 yards (1,370 m), decrease wind deflection on bullets in flight and use Hodgdon H1000, a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of −25 °F to +165 °F (−32 °C to 74 °C). (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the .300 Winchester Magnum can handle up to 430.00 MPa (62,366 psi) Pmax piezo pressure. The ability to zero the .300 Winchester Magnum and shoot without hold over to 270 metres (300 yd) makes the cartridge one of the flatter shooting cartridges. The down side was a neck which was shorter than the caliber of the bullet it fired, which meant that the bullet had to be seated more deeply in the case. Like other .300 caliber in its class the .300 Win Mag was popular almost immediately after it was introduced on the commercial market. 300 Winchester Magnum: How Does Barrel Length Change Velocity- A 16″ 300 Win Mag? The Winchester's factory ammunition for the .300 Winchester Magnum is capable of 990 m/s (3,260 ft/s) with the 150-grain (9.7 g) bullet and 910 m/s (3,000 ft/s) with the 12-gram (180 gr) bullet, however old Western "Power Point" soft point can reach past 1,000 metres per second (3,400 ft/s) with 9.7 g (150 gr) projectiles. In 1958 Winchester introduced three cartridges – the .264 Winchester Magnum, .338 Winchester Magnum and the .458 Winchester Magnum, all based on the shortened and blown out .375 H&H Magnum case. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) have provided specifications for the .300 Winchester Magnum cartridge. The .300 H&H Magnum was too long for the Mauser and Springfield standard length rifle actions and required specialized rifles with a Magnum size action. Recoil from the .300 Win Mag is noticeably higher than the well-known and popular .30-06 Springfield. Compared with the 30-06 Springfield the .300 Winchester Magnum provides a roughly 400 ft/s (120 m/s) increase in velocity. [13], The .300 Winchester Magnum cartridge is very effective on dangerous class 3 game such as bear. The introduction of the .300 Winchester Magnum was not unforeseen; rather, its introduction was anticlimactic[citation needed]. The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62 mm) cartridges. Federal 92.0 grains of H2O (5.96 ml) Sub 1 minute-of-angle (MOA) accuracy out to 1,000 yards (910 m) is not unusual in precision-built rifles firing match-grade ammunition. regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. Winchester 93.8 grains of H2O (6.08 ml) This greater recoil can make the .300 Winchester Magnum, despite its inherent accuracy advantages, a harder cartridge to shoot accurately, when compared to non-magnum .30 caliber cartridges such as the .30-06 Springfield or the .308 Winchester. 115 SW Columbia St | Bend, Oregon, USA 97702  |  Toll Free: Nosler Showroom / Open to the Public:  Monday - Friday 10:00 am to 5:30 pm PST, Load Data &Technical Information by Cartridge.

The .300 Weatherby Magnum was introduced in 1944. The .300 Winchester Magnum (also known as .300 Win Mag or 300WM) (7.62×67mmB) is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet. The case volume will vary from manufacturer to manufacturer to such a degree the reloading software suite QuickLOAD provides five differing cartridge case capacities, that for reloading purposes significantly differ between manufacturers. Taken together with its performance it remains one of the most useful and popular cartridges today. The maximum point blank range for the 9.7 g (150 gr) bullet is 291 metres (318 yd) yards when zeroed at 250 metres (270 yd). The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum. The down side to this performance is recoil. 220 Swift Load Data; 223 Win Super Short Magnum (WSSM) Load Data; 6mm PPC-USA Load Data; ... 300 Weatherby Magnum Load Data; 30 Nosler Load Data; 30-378 Weatherby Magnum Load Data; ... 100 - 110 Grain; 130 Grain; 140 Grain; 150 Grain; 160 Grain; Cartridge Information.

If Winchester had released the cartridge prior to 1960, the cartridge would have been similar to the .30-338 Winchester wildcat cartridge. The fact that the cartridge has gone to win many 1,000-yard (910 m) matches suggests that such a concern is unfounded. You can also click on the image and a pdf version will open in a new window.

Although cartridges such as the .30-378 Weatherby Magnum, .300 Remington Ultra Magnum and the .300 Weatherby Magnum all exceed performance of the .300 Winchester Magnum none of these cartridges can be chambered in a standard length action. Also, many rifles available today now have effective recoil attenuating features built into them, such as muzzle compensators and energy absorbing stocks and butt-pads, that can significantly lessen recoil as it is felt by the shooter. The Weatherby cartridges involved blowing out (reducing the taper) of the Magnum H&H cases, bottlenecking them to the required caliber and shortening them to fit the standard rifle actions of the era. All sizes in inches (in) and millimeters (mm). In fact, it was because of these limitations that Weatherby chose the .30-06 cartridge case as the parent case design for the .240. Controlled expansion bullets such as the Nosler Partition or Barnes X are preferred rather than more lightly constructed bullets for these larger species of ungulate. The .300 Win Mag sees use in long-range benchrest shooting competitions and has been adopted by law enforcement marksmen and by a few specific branches of the U.S. Military for use by snipers. Live fire tests were conducted in March 2013 against ballistics gelatin, light material barriers, and other targets to determine the projectile's ability to perforate targets.

HUSH 300 Blackout 220 gr HPBT New The 300 Blackout cartridge (often referred to as 300 AAC, 300 AAC Blackout, 300 BLK or simply Blackout) was designed and developed to be used in suppressed firearm platforms utilizing a 220 grain projectile. However, the handloader can take advantage of modern advances in powder technology and actually exceed the velocity of the MK 248 MOD 1 cartridge while still loading to maximum SAAMI cartridge overall length, and maintaining safe pressure. The .240 is essentially the .30-06 necked down to 6mm (.243”) with a belt added (for a ‘magnum’ appearance) and a double radius improved shoulder. This was the first time the Pentagon's Director, Operational Test and Evaluation (DOT&E) tested the round, which can hit targets out to 1,200 m (1,312 yd).[23]. This means that .300 Winchester Magnum chambered arms in C.I.P. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. pressure to certify for sale to consumers.
